Hemodynamics　is　closely　related　with　the　initiation,　development　and　treatment　of　neo-cardiovascular　diseases.　The　studies　on　the　hemodynamics　in　neo-cardiovascular　system　are　the　hotspots　of　biomechanics　and　biomedical　engineering.　The　research　topics,　research　method,　research　achievement　and　its　medical　application,　which　are　issued　in　the　articles　in　this　special　column,　were　remarked.　Emphasis　was　paid　to　the　review　of　the　research　driver,　research　progress　and　research　tendency　of　hemodynamics.　The　application　prospect　of　hemodynamics　research　on　the　clinical　procedure　and　healthcare　was　demonstrated　with　respect　to　its　multi-level　application　in　prevention,　diagnosis　and　treatment.
